Another novel find is that populations of Homo erectus in Eurasia had recurrent genetic interchange with African populations 1.5 million years ago, much earlier than previously thought, and that these populations...

The Amazon in 2050: Implementing the law could save a million square kilometers of rainforest

...ss of mammals will be in the eastern Amazon, where expanding agriculture will overrun many species with small ranges. Of the major highways planned for paving, the Manaus-Porto Velho highway will be the most damaging in terms of new deforestation. The challenge of Amazon conservation is to find ways to redi...

A salty tale: New bacterial genome sequenced from ancient salterns

...The two systems may work at different wavelengths, expanding S. ruber's ability to thrive in this environment. Alternatively, Mongodin says, the double system may be redundant, a kind of biological back-up. Because S. ruber grows in high salt, its enzymes are strikingly stable. And that means the bacterium m...
